小题1:主旨大意题。从第一段的：“More than hard work or education, the best way to get rich in America is to be born rich.”和最后一段的：“for the millions of people who find themselves below the poverty line and the millions more who are the working poor, their starting point for the American dream leaves them painfully far away from the middle class”可知答案。
小题2:细节判断题。用排除法，根据倒数第二段的：“If you started in the middle-income class, about 40 to 45 percent of what you are making right now is due to the fact that your parents were in the middle-income class. The rest is up to you.”可知，还有相当部分取决于你，而不是你父母。所以C选项不正确。
小题3:词义猜测题。根据下一段的：“If you started in the middle-income class, about 40 to 45 percent of what you are making right now is due to the fact that your parents were in the middle-income class. ”可知答案。
小题4:细节理解题。根据第一段的的：She may be right 因为“More than hard work or education, the best way to get rich in America is to be born rich.”
小题5:推理判断题。通阅读全文，特别是第一段和最后一段可知答案。
